The Sun Hydraulics PBJBWBV (PBJBWBV) is a pilot-operated, pressure reducing valve designed to efficiently manage hydraulic systems with varying pressure requirements using a single pump. This versatile valve reduces high primary pressure at inlet port 2 to a consistent lower pressure at port 1, making it suitable for circuits needing multiple pressure levels. Notably, all three-port pressure reducing and reducing-relieving cartridges are interchangeable within the same frame size, offering flexibility in system design. For configurations requiring reverse flow from reduced pressure port 1 to inlet port 2, it is recommended to incorporate an additional check valve to prevent the main spool from closing. The valve features a protected main stage orifice with a 150-micron stainless steel screen and operates optimally with recommended maximum inlet pressures based on specific adjustment ranges. The PBJBWBV exhibits stable performance with low hysteresis and exceptionally flat pressure-flow characteristics, although it's not intended for fast-acting applications; for those needs, direct acting valves are suggested. It incorporates Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. The valve's cavity is T-19A, Series 4, with an impressive capacity of up to 80 gpm (320 L/min), and it can handle maximum operating pressures of up to 5000 psi (350 bar). Adjustments are facilitated by a screw with internal hex size of 5/32 inches and secured by a locknut torqued between 80-90 lbf-in (9-10 Nm). Additionally, the cartridge is compatible with Viton seals for durability in various fluid environments.

Pilot-operated, pressure reducing valves reduce a high primary pressure at the inlet (port 2) to a constant reduced pressure at port 1, allowing circuits with multiple pressure requirements to be operated using a single pump.
- All three-port pressure reducing and reducing/relieving cartridges are physically interchangeable (i.e. same flow path, same cavity for a given frame size). When considering mounting configurations, it is sometimes recommended that a full capacity return line (port 3) be used with reducing/relieving cartridges.
- Full reverse flow from reduced pressure (port 1) to inlet (port 2) may cause the main spool to close. If reverse free flow is required in the circuit, consider adding a separate check valve to the circuit.
- If pilot flow consumption is critical, consider using direct acting reducing/relieving valves.
- Main stage orifice is protected by a 150 micron stainless steel screen.
- Recommended maximum inlet pressure is determined by the adjustment range. Ranges D, E, N, and Q are tested with a 2000 psi (140 bar) maximum differential between inlet and reduced pressure. Ranges A, B, and H are tested with a 3000 psi (210 bar) maximum differential between inlet and reduced pressure. Ranges C and W are tested with 5000 psi (350 bar) of inlet pressure.
- Pilot operated valves exhibit exceptionally flat pressure/flow characteristics, are very stable and have low hysteresis.
- Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar).
- Pilot operated reducing, reducing/relieving valves by nature are not fast acting valves. For superior dynamic response, consider direct acting valves.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
